About Kilogram-force (kgf)
A legacy metric unit of force equal to the gravitational pull on a 1-kilogram mass at the standard acceleration of gravity g₀ = 9.80665 m/s² (CIPM Resolution 2, 1901), giving exactly 9.80665 N per kgf. Although officially deprecated in favor of the newton under ISO 80000-4 and BIPM SI Brochure §5.4.1, kgf persists in identifiable contexts: tire-pressure gauges in some European countries (a tire pressure of "2.2 kgf/cm²" appears on Russian and Eastern-European specs), industrial-press tonnage ratings expressed in tonnes-force (where 1 tf = 1,000 kgf = 9.80665 kN), cable-tension and lifting-equipment markings in Japanese and older Soviet/Russian engineering drawings, legacy ASME pressure-vessel international-equivalence tables, and motorcycle/bicycle gear-train torque ratings in older European literature. Converting kgf to newtons is multiply by exactly 9.80665; to lbf is multiply by 2.2046.
About Dyne (dyn)
A CGS (centimeter-gram-second) unit of force equal to exactly 10 micronewtons (10⁻⁵ N), originally defined as the force required to accelerate 1 gram of mass at 1 cm/s². The dyne is the CGS analog of the newton; CGS itself was the dominant scientific-unit system from ~1873 until SI's adoption in 1960. Dynes are largely obsolete in modern engineering but persist in identifiable specialty fields: surface-tension measurements where "dyn/cm" is still the conventional liquid-interface unit (water at 20 °C: 72.8 dyn/cm; mercury: 472 dyn/cm; ethanol: 22.4 dyn/cm) — the conversion to SI is 1 dyn/cm = 1 mN/m so no numerical change is needed; older chemistry and biochemistry literature (especially pre-1970s); some astrophysics and plasma-physics papers where CGS-Gaussian electromagnetic units remain conventional; and tribology/colloid-science journals (the Journal of Colloid and Interface Science still accepts dyn/cm).

Understanding Dynes
The Dyne (symbol: dyn) is a unit of force. A CGS (centimeter-gram-second) unit of force equal to exactly 10 micronewtons (10⁻⁵ N), originally defined as the force required to accelerate 1 gram of mass at 1 cm/s². The dyne is the CGS analog of the newton; CGS itself was the dominant scientific-unit system from ~1873 until SI's adoption in 1960.
